A regenerative biostimulant platform designed to improve nutrient efficiency, strengthen soil biology and increase crop performance.

BF4® is Agritein’s advanced biostimulant platform that combines marine algal extract, amino acid complexes and soil microbial activator to improve plant performance and soil health. Designed for integration into modern fertility programs, BF4® enhances nutrient uptake, stimulates root development and supports consistent yield improvements across a wide range of crops.

Helps plants access and utilize nutrients more effectively, maximizing return on fertilizer investment.

Promotes stronger, deeper root systems for better water and nutrient uptake.

Helps crops perform under environmental stress such as heat, drought and nutrient limitations.

Activates beneficial microbial activity in the rhizosphere to improve long-term soil health.

Supports measurable improvements in crop yield and quality under real-world conditions.

How it Works

BF4® delivers performance through a multi-action approach.

Plant activation. Amino acid complexes stimulate plant metabolic processes, improving growth efficiency and resilience.

Biological soil support. Beneficial microbes enhance nutrient cycling and create a more active soil ecosystem.

Natural growth stimulation. Marine algal extract provides plant hormones and micronutrients that support vigor and development.
